Death Pill

Feel yourself being Sherlock Holmes, playing a game of chess, with one move to death. There's a good pill and a bad pill. You take the good pill - you live; take the bad pill - you die. The most interesting thing about it: whatever pill you choose, your rival have to eat the left one.

Did your rival just give you the good pill or the bad pill? Is it a bluff? Or a double-bluff? Or a triple-bluff? 1 game, 1 move, 1 survivor.

Dont play fifty-fifty chance!!! Your rival can ask for any clarification. For example,he can ask if the good pill is here (or maybe it is there). And try to catch your rival on lies!!!
Do your best not to get the pill of death!
